In-depth Reviews

Thorne Basic Prenatal

Form
Capsules
Daily serving
3 capsules
Folate
1,000 mcg (as 5-MTHF)
Iron
45 mg
Choline
110 mg
Real Talk: This is a high-coverage prenatal that feels like the “no gaps” option when you want one supplement to do most of the heavy lifting. It tends to suit people who like active forms of key nutrients and want a formula that aligns with common clinical preferences. The trade-off is tolerability: the stronger profile can feel intense if you are prone to nausea or constipation, so taking it with food is often key.
✅ Pros
  • Robust nutrient coverage that can reduce the need for add-ons
  • Uses active folate form many people prefer
  • Works well for those who need more iron support
❌ Cons
  • Multiple capsules per day can be annoying
  • Higher iron may be harder on sensitive stomachs

Ritual Essential Prenatal Multivitamin

Form
Delayed-release capsules
Daily serving
2 capsules
Folate
1,000 mcg DFE (as 5-MTHF)
Iron
18 mg
DHA
350 mg
Real Talk: If you want a prenatal you will actually remember to take, this one is built around simplicity and a predictable daily routine. It is often a good fit for people who dislike swallowing a handful of pills and want omega-3 support included. The flip side is that it is intentionally streamlined, so depending on your diet and labs, you may still need separate choline, calcium, or other targeted supplements your provider recommends.
✅ Pros
  • Simple daily routine that is easier to stick with
  • Includes omega-3 DHA in the same supplement
  • Often gentler than heavier, high-iron formulas
❌ Cons
  • Lean formula may require add-ons for some people
  • Capsules can feel large if you struggle to swallow pills

Nature Made Prenatal Multi + DHA

Form
Softgel
Daily serving
1 softgel
Iron
27 mg
Folic acid
800 mcg
DHA
Included
Real Talk: This is a straightforward, mainstream prenatal that works well for people who want a classic one-and-done option with DHA included. It is easy to find and easy to understand, which matters when you are replacing supplements in a hurry. Like many fish oil containing prenatals, some people notice fishy burps or a lingering taste, so taking it with a full meal (or at night) can make a big difference.
✅ Pros
  • One softgel daily keeps routines simple
  • Includes DHA without adding another bottle
  • Widely available and easy to repurchase
❌ Cons
  • Fishy aftertaste is possible
  • May feel heavy if taken without food

One A Day Women’s Prenatal 1 Multivitamin

Form
Softgel
Daily serving
1 softgel
DHA
Included
Iron
Included
Folate/Folic acid
Included
Real Talk: If cost and convenience are driving your decision, this prenatal is a practical choice that covers the basics without requiring a complicated plan. It is especially helpful for busy schedules because it is simple to take consistently. The most common downside is tolerability: if you are sensitive to iron or you already struggle with nausea, you may need to take it only with a substantial meal or consider a different formula your clinician approves.
✅ Pros
  • Budget-friendly option that still covers major prenatal basics
  • Simple, consistent once-daily habit
  • Easy to find in many stores
❌ Cons
  • Can trigger nausea if taken on an empty stomach
  • Less flexible if you want to customize nutrients

MegaFood Baby & Me 2 Prenatal Multi

Form
Tablets
Daily serving
2 tablets
Iron
Included
DHA
Not included
Routine type
Prenatal-only (add DHA separately if desired)
Real Talk: This is a solid pick if you prefer a tablet-style prenatal and want something many people find easier to tolerate, especially when taken with food. It can also be a good match if you like to build your routine in pieces, pairing your prenatal with a separate DHA supplement you personally tolerate well. The main drawback is that it is not a one-pill solution, and it does not replace omega-3 support on its own.
✅ Pros
  • Often well tolerated with meals
  • Pairs easily with a separate DHA you like
  • Good option if you dislike softgels
❌ Cons
  • Multiple tablets per day
  • No built-in DHA

What We Wish More People Knew Before Picking a Prenatal

Consistency beats perfection. The “best” prenatal on paper is not the best prenatal if you dread taking it. Before you switch brands, try changing timing and food: many people do best taking their prenatal after dinner or right before bed, and almost nobody does best taking it on an empty stomach during the first trimester.

Watch the common friction points: iron, fish oil, and pill burden. Iron is frequently the culprit behind nausea and constipation, while DHA can cause fishy burps. If your current prenatal is otherwise a good fit, a small routine tweak can help, like splitting the serving (if allowed) or taking the DHA component with a heavier meal. If you are already on an iron supplement or you have a thyroid condition, ask your clinician about spacing supplements since iron and calcium can interfere with absorption of certain medications.

Plan for “add-ons” on purpose, not by accident. Some prenatals are comprehensive, while others assume you will cover certain nutrients through food or targeted supplements. If your prenatal is minimalist, decide upfront whether you are willing to add separate DHA or choline so you do not end up with an inconsistent mix of half-finished bottles. Finally, if you take other supplements, scan for overlap, especially vitamin A forms and high-dose single nutrients, and confirm your full stack with your OB-GYN or midwife.

💡 Editor’s Final Thoughts

Final verdict: Thorne Basic Prenatal is our top pick for most people because it delivers robust, clinic-style coverage with forms many providers like, which can reduce the need for extra bottles. If you want the simplest daily habit with DHA built in, Ritual Essential Prenatal is an excellent, easier-to-stick-with alternative.

Frequently Asked Questions ▾

When should I start taking a prenatal multivitamin?

Many clinicians suggest starting before you conceive or as soon as you think pregnancy is possible, since early development happens before many people get a positive test. If you are already pregnant, starting now is still worthwhile because key nutrients support you and baby throughout pregnancy.

If you are switching from a regular multivitamin, bring the label to your OB-GYN or midwife so you do not accidentally double up on overlapping nutrients.

Do I need DHA in my prenatal, or can I add it separately?

You can do either. A prenatal that includes DHA is convenient because it reduces the number of bottles and helps you stay consistent on busy days. If your prenatal does not include DHA, adding a separate DHA supplement can work well, especially if you prefer to choose the type (algae-based or fish oil) that your stomach tolerates best.

If you already eat low-mercury fatty fish regularly, ask your provider whether you still need supplemental DHA and what dose makes sense for you.

What if my prenatal makes me nauseated?

First, change how you take it before you change the brand. Try taking it with a solid snack or after dinner, and consider splitting the serving across morning and evening if the label allows it. Many people also find that taking prenatals right before bed helps because they sleep through the “queasy window.”

If nausea persists, talk with your provider about trying a different iron level or form, since iron is a common trigger for sensitive stomachs.

Can a prenatal multivitamin cause constipation?

Yes, and iron is often the reason. If constipation shows up, increase fluids and fiber first, and consider taking your prenatal with food instead of on an empty stomach. Some people do better splitting the dose, while others do better switching to a lower-iron prenatal and taking iron only if labs show they need it.

Check with your OB-GYN before making big changes, especially if you have a history of anemia or you are already being monitored for iron levels.

Is a “clean” prenatal automatically better?

Not necessarily. What matters most is that the prenatal fits your needs, is well tolerated, and provides the nutrients your clinician expects you to be getting, especially folate, iodine, iron (when appropriate), and vitamin D. Some minimalist formulas feel great to take but may leave you needing separate add-ons, which can reduce consistency.

Instead of chasing buzzwords, focus on the label, your labs, and whether you can realistically take it most days without side effects.
